" This invention relateslto paper niaking chinery and moreparticularly't'o the heads of the'suction boxes of said machinery, andhas for one of its obj ects to provldei n a'nian- -5 her asv hereinafterset forth, a head iof the aforementioned character, having means I vthereon forco-action with means on a detachable handle or rod wherebyan" extremely socket which mounted on the suetion Fi'gurevifi is a sideelevation,ipartlybroken' L away in section, of the upper end ofthehanrod"; 3

strong connection is had between the handle Another important object ofthe" invention is to providea'suctio ibx head or'ldecklehaving adetachable handlewhijdhfmaybe removed after the head is'adjustedor set,-thus f be used for any number of heads;- I

Another objectof the invention is to provide a suction box head ordeckle embodying means for detachably connecting a c handle 20 theretowithout the necessity o f forming an opening through the head for thepassage of the handle and through whichthe fluid may The invention aim sto provide a suction box dle rod or shaft; which; is inserted inthe oSocket 1.," H n Y. v

Theopposite end of the 7 tube 14 is open and is provided with oppositelydisposedibayonet slots 16. A bifurcated 1 reinforcing cylinder 17 isrotatably mounted In the upper end of the tube 14, and is provided,adjacent its'lowerend with, an annular groove 718. The slot 19 which isformed by 20 is mountedin the tubes 14 and projects in--wardly.therefromand extends into the annu- ,thebifurcatedendofthe-cylinder is adapted for alignment with the bayonet slot 16 ofthe tube 14, and is coextensivewith the longitudinalportlons of-saidbayonet slots.

. through themedium of a crosspin 22, and interposedbetween thestops 21and lower end of the cylinder 17 is an expansible coil spring Inthe useof the invention,the socket 4 is mounted on the neck 3 and the brackets9v are then mounted in place on the head 1, as clearly shown'inFigurelofthe drawings. I The-slotted end of the tube let is then placed theboreof the socket 4; and-pushed upcross-pin 12,

lwardly therein, the furcations on: the ends thereof extending on"opposite sides of the Whenthe'lower ends of the bayonetslot 16 engagethecross pin 12, a slightturn is imparted to the tube 14 for seating thecross pin 12 in the right angularly disposed lower end portion of thebayonetslot, as willbe understood. It will be here pointed out that theannular groove 18 inthereinforcing cylinder 17 is of greater diameterthan the retaining screw ,20,'and it will therefore be seen that a veryslight longitudinal movement of the, reinforcingjcylinder inthe tube may.be had.

By reason of this, when the cross pin 12 has beensea'ted in the rightangularly disposed pocket ofthe bayonet slot, the reinforcing cylinder17' which is causedto rotate in the tube 1 the pin 12,,whichalsotraverses the recess 19 in said cylinder, serves to close theoffset portionsof the bayonetslot and said cylinder is frictionally{held against rotation by the I pressureexerted by the coil spring 23.It is of, course, understood that the friction providedby the 'coilspr-ing23 is not great enough by hand.
